The NVIDIA RTX A6000 GPU is particularly interesting due to a key omission. This was originally set to be a “Quadro” brand product. In a last-minute change, the “Quadro” designation was dropped, even though it is a card typically found in that segment. We see this as perhaps an update to the NVIDIA Quadro RTX 6000 if not maybe the NVIDIA Quadro RTX 8000 we reviewed (also with two in NVLink.) We confirmed with NVIDIA that the company is phasing out the Quadro branding as they did with the “Tesla” brand in 2019. We were told the “Tesla” brand was phased out to reduce confusion with the car brand, but we are less certain what the Quadro brand would conflict with.
NVIDIA RTX A6000 48GB GPU
With the NVIDIA RTX A6000 we get a 48GB GDDR6 GPU. We typically see GDDR memory in this space instead of HBM2 as this is an actively cooled card. TDP on the card is raising to 300W continuing a trend towards higher-power GPUs.

Something we thought was interesting is that NVIDIA is listing GDDR6 memory, not GDDR6X memory as we saw with the higher-end NVIDIA GeForce RTX 3000 series GPUs. We would have expected to see GDDR6X on the higher-end GPUs.
Power and cooling for a 300W GPU, or perhaps, more importantly, multiple 300W GPUs is harder than many of the older generations. Not only are we seeing TDP creep in the data center on CPUs and GPUs, but we are also going to see more in higher-end workstations. Although many of the specs are similar between this and the NVIDIA A40, the memory bandwidth his higher on the RTX A6000 with 768GB/s versus 696GB/s on the passively cooled GPU.
